WASHBOARD.

Application 'led December 20, 1920. Serial No. 432,151.

To all /w/wm t may. Gomera.'

Be it known that JULiUs JUDELsoN, citizen of the United States, and resident of the city of New Y'orlr, in the .county of'Bronx and State of New York, has invented .certain new and useful Improvements in Tashboards. of which the following is a specification. v

This invention relates to wash-boards.

One object thereof is to provide a device of the character described which shall have a rubbing sur-face adapted to effectively cleanse the clothes without subjecting the latter to any sharp edges or corners that may cut or otherwise harm the clothes or the hands of the operator.

Another object is to provide a device of this type which shall be simple in construetion, cheap to manufacture, and eflicient in operation.V4 H i Other objects of this invention will be in part obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter described and of which the scope of invention will be indicated in the following claim.

1n the accompanying drawings, in which is shown one of various possible illustrative embodiments of this invention,

Fig. 1 is a front elevation of a wash-board embodying this invention;

Fig. 2 is an end elevation thereof showing the wash-board inclined in the position it takes in the wash-tub;

Fig. 3 is a horizontal cross-section through the rubbing surface taken along line of Fig. 1;

Fig. L1 is an enlarged detailed sectional view-similar to Fig. 3 of a portion of the rubbing surface; and

Fig. 5 is an enlarged partial vertical elevational view of the rubbing surface.

Referring in detail to the drawing, the washboard embodying my invention' there shown, is seen to comprise a head piece 10 and side rails 11 between which extends the rubbing plate 12 hereinafter more particularly to be described. The said rails 11. preferably extend beyond the rubbing plate so as to provide legs 13, 13 for supporting the wash board in the tub, as will be readily understood. I

The `construct-ion of the rubbing board 12 willr now be described in detail. This consists of a plate 14. preferably of metal on which are embossed rubbing elements 15 preferably in the form of smooth convexly curved ring portions 16 upstanding from the plate. Togive stiffness to these raised portions 16, the metal is curved downwardly in the reverse direction, that is, concavely from these convex portions, resulting in aring 1T concentric with the ring 16 as will` be readily understood, and smoothly continuous therewith, as at 17. In constructing the washboard in practice, these rubbing elements 15 are struck from the metal preferably by a die and simultaneously with the formation of the concentric rings 16 and 17 there are formed concentric therewith the perforations 1S. These perforations serve to allow the water to drip through the rubbing board into the tub While the clothes are being washed. Further, the water in the tub is enabled thereby to come in contact with the clothes both from the inside thereof and the side facing the operator.

In the formation of the rubbing elements in the manner hereinbefore described, there is a sharp edge 19 forming the periphery of the perforation as will be readily understood. The counter-sunk concave rings 1T prevent the clothes or the hands of the operator from coming into contact with this sharp edge, while the convex rings 16 provide the necessary rubbing surface for cleansing the materials.

In the embodiment shown in the drawing the head piece 10 and side rails are formed continuous with the rubbing board 12, the latter being suitably bent to provide the head piece 20 and rectangularly as at 21 to provide the side rails. For giving stiffness to the side rails, bars 22 are inserted into the hollow rectangular portions 21 as is clear from Fig. 3. At the base of the rubbing board in the rear portion thereof, is a horizontal stiffening bar 23 for giving strength thereto. For further strengthening the frame, vertical bars 24 are secured in a suitable manner on the rear face of the board adjacent the side rails 11 as will be cbeqaqr from said figure.

he head piece 20 is provided with a suitable soap holding ledge 25 bent rearwardly from the rubbing board 12, the rear upstanding wall of said head piece 2O being disposed in a plane at an acute angle with respect to the said plate. Said head piece 2O is constructed to have its upper edge overturned to form a rounded bearing surface for contacting with the operators body and to form a transverse brace for the device. (See Figs. 1 and 2.) Thus the head piece 20 provides a soap holding means set back from the front of the rubbing board 12 so as not to interfere with the washing operation, and the rear side of the ledge 25 may engage over the rim oit' the tub (not shown) to serve as stop means for retaining the wash board in position.

The bottom of the legs 13, 13 may further be provided with rubber padding 26 to prevent the legs from injuring the walls of the tub.

It will thus be seen that there is provided apparatus in which the several objects of this invention are achieved and which is well adapted to meet the conditions or' practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting Sense.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 2- In a wash board construction, a frame comprising side and cross members, a rubbing plate secured to the frame, a plurality of uniformly spaced rubbing elements being formed on said plate, stiffening means formed integral with the outer edges of said rubbing plate, said means comprising a head piece, bottom and side portions, said bottom and side portions being bent about the frame, said head piece being bent rearwardly of the rubbing plate to form a soap holding ledge, then upwardly, the upstanding wall of said head portion being disposed in a plane at an acute angle with respect to the rubbing plate, and the upper edge of said wall being overturned to form a rounded bearing surface, said ledge shaped to overhang the rear side of the board to serve as a stop means to retain the wash board in position.

Signed at New York city, in the county of New York and Sta-teef New York, December A. D. 1920.

JULIUS JUDELsoN.
